Magnetic Force Microscopy of Micropatterned Clusters of Superparamagnetic Iron Oxide Nanoparticles.
Article in ACS applied nano materials, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Magnetic force microscopy (MFM) was used to characterize micropatterned clusters of superparamagnetic iron oxide nanoparticles (SPIONs). Top-down lithography was used to create SPION aggregates with well-defined geometries. The micrometer-scale aggregates exhibited different properties from individual particles and from smaller clusters containing just a few particles. The MFM phase shift from magnetic interactions between the sample and probe tip could be detected at lift heights of several hundred nanometers. The experimental data was compared to a magnetic dipole-dipole interaction model to understand the relationship between MFM phase shift and lift height. Magnetic interactions between the probe tip and the sample also led to an apparent "ballooning" of the feature size, where the aggregates appeared larger with MFM than their physical size obtained from scanning electron microscopy. These results can guide emerging applications of MFM, such as the detection of SPIONs within biological environments.
